This invention relates to a process for producing electron deficient olefins, such as 2-cyanoacrylates, using an acid catalyzed Knoevenagel condensation reaction.

Process for preparing electron deficient olefins

This invention relates to a process for producing electron deficient olefin precursors, such as 2-cyanoacetates, using an acid catalyzed esterification reaction.

Process for preparing electron deficient olefin precursors

This invention relates to a process for preparing electron deficient olefins, such as 2-cyanoacrylates, using an acid catalyzed two-step process including an esterification reaction followed by a Knoevenagel condensation reaction.

This invention relates to a process for preparing electron deficient olefins, such as 2-cyanoacrylates, using an acid catalyzed two-step process including a transesterification reaction followed by a Knoevenagel condensation reaction.

This invention relates to a process for producing electron deficient olefin precursors, such as 2-cyanoacetates, using an acid catalyzed transesterification reaction.

Allyl-cyanoacrylate-containing compositions with an anhydride aromatic component, which when cured confers improved moisture resistance, are provided.

Cyanoacrylate compositions

This invention relates to cyanoacrylate-containing compositions, which when cured provide improved heat resistance.

Cyanoacrylate-containing compositions that include, in addition to the cyanoacrylate component, a hydrogenated anhydride and optionally a benzonitrile, are provided. Cured products of the inventive cyanoacrylate compositions demonstrate improved heat resistance without compromising fixture time, stability or color.

The present invention relates generally to cyanoacrylate adhesives and, more particularly, to a one-part adhesive, comprising one or more 2-cyanoacrylate esters, one or more bis-silanes and optionally one or more monosilanes and to the use of said adhesive as an instant adhesive with improved water resistance.
